It has come to our attention that a certain artifact that once was believed to be mythical may, in fact, be real. Your presence at the London offices of the Royal Geographic Society is requested. Please be at our office on Friday at 4:00 P.M. London time. More details will be provided upon your arrival. Bring only yourself and your equipment, the Society will provide other material as needed.
